History
Erected on 31 January 1970 out of the then Roman Catholic Diocese of Tuguegarao, the Diocese of Ilagan (Latin: Dioecesis Ilaganensis) is a Latin Catholic diocese of the Philippines covering the whole civil Province of Isabela. Because Tuguegarao was not yet a metropolitan diocese when Ilagan was created, the new see fell under the jurisdiction of the Archdiocese of Nueva Segovia.
